Hello Santosh Again,

 1 . You can edit your form by clicking Edit Form in My Forms page.

2 . You can click to anywhere belong to Submit area.

3 . Then click the sign representing settings.

4 . You can Duplicate the field you want which is under the heading General but be aware that the area you want (for your case it’s submit) is selected already.

5 . You can change the style and color of the submit button from Button Style.

6 . To make detailed adjustments to submit button you can also use Button Text, Button Alignment and if you want to use your own creation you can use Button Image part.
